GMII to RMII Converter usage restrictions

Hi,

The timing fails only for RGMII with Triple Speed Ethernet. So the RGMII interface is not supported in Stratix® 10, Arria® 10, and Cyclone® 10 GX devices from Quartus® Prime software version 17.1 onwards check this link https://www.intel.com/content/www/us/en/docs/programmable/683402/24-3/core-configuration.html

There's no problem with the HPS IO.

Thanks,

Regards,
